Initial tetrahedral mesh has 13,453 vertices, all on the boundary surface.

Triangular boundary surface mesh of the initial mesh.

There are 15,503 tetrahedral elements with minimum dihedral angle less than five degree.

After sink-insertion, 1,183 small slivers survived.

There are 142 slivers left after sliver-exudation.
Number of tetrahedra is decreased from 291,122 to 282,633.
Overall distribution of minimum dihedral angle is also improved.
